The ag. sector says big strides have been made in research to reduce climate emissions, but considerable uncertainty remains about when the technology will actually be available for farmers. Harry Clark runs the Agricultural Greenhouse Gas Research Centre and says reducing emissions on the farm without reducing the amount of milk or meat produced is an intricate interplay between animals, the weather and climate, and inputs like fertilisers. Harry Clark says there are technologies coming along to help address the issue of agricultural greenhouse gases including a feed that reduces animal methane emissions by a third. It will be available in Aotearoa NZ in two years. There is also the selective breeding of low emissions animals, which could add up to 10 percent reductions over 10 years and the real game changer – a potential methane vaccine, which won’t be available until the middle of next decade.
